问题 I am trying to convert an existing app to the new 3.1 asset pipeline layout, and want to include a lot of vendor files that have to be in a specific order, (underscore.js and backbone being one pair).

Using Rails 3.1, where do you put your “page specific” JavaScript code?

阅读更多关于 Using Rails 3.1, where do you put your “page specific” JavaScript code?

问题 To my understanding, all of your JavaScript gets merged into 1 file. Rails does this by default when it adds //= require_tree . to the bottom of your application.js manifest file. This sounds like a real life-saver, but I am a little concerned about page-specific JavaScript code. Does this code get executed on every page? The last thing I want is for all of my objects to be instantiated for every page when they are only needed on 1 page. Also, isn\'t there potential for code that clashes too?
